SEALING DEVICEl FOR WRAPPERS.

Application filed January 15, 1923. Serial No. 612,874.

To all whom t may concern Be it known that l, JAMES B. Romains, a citizen of the United States, residing at (Jrowley, in the parish of Acadiav and State of Louisiana, have invented new and useful Improvements in Sealing Devices for Wrappers, of which the following is a specilication.

For sanitary reasons, baker-s bread is re quired in several States of the Union to be encased .in a wrapper before delivery from the baker. The wrapped bread must be sealed. Bakers have found waxed paper to be hygienic as well as an air-tight casing and therefore a preservative t'or bread wrapped therein, and it is the object of this invention to provide a simple, cheap and effective means in the natu-re of a chute through which the wrapped bread is caused to pass and which is provided with means for tirst heating the wrapper to soften or melt the wax on the folded ends and edgeof the wrapper to create an adhesive agent. and thereafter subject the wrapper, to the influence of a. cool temperature to harden the softened wax, and thus edectively seal the package.

T o the attainment. of the foregoing and other objects which will present' themselves as the nature ot the invention is' better understood, reference is to be had to the drawings which accompany'and which form part ot this application.

ln the drawings:

Figure l is a perspective view of the improvernent, showlng the heating trough restinf; on a stove. f

Figure 2 is a transverse sectional view through the heating trough..

Figure 3 is a similar sectional view through the cooling trough.

Figure t is a sectional view approximately ont the line 4 4 of .Figure l.

Figure 5 is a sectional view approximately on the line 5 -5 of Figure l.

As disclosed by the drawings, l make use of two troughs, l and 2 respectively. The trough 2 is ot a greater length than the trough l, but in other respects, the troughs are equally proportioned. Each trough is inthe nature of a hollow shell, the trough Il being preferably constructed, of Inet-al, but the trough 9: may be constructed of other material, if desired.

Each trough includes a flat base oomprisof course, upper and lower walls,` and right angular' opstanding sides which lilreY wise comprise spaced walls. The top and edges secure the spaced walls of the base and sides in proper spaced relation to cach other, andV the distance between the walls equals the length of a bakers loa-t a'lfter'the same has been wrapped in YaXed paper.

The trough 1 has one ot its sides at the top thereof provided with a water inlet. openingvr and the same being closed by a. screw cap 3. The opposite side wall ot the trough 1 has an opening in which is screwed, soldered or otherwise secured a blow-oil valve 3', and this `valve is always retained in an open condition when the trough 1. is arranged upon a heater et as disclosed in -lfigure l of the drawings.l

' The trough 2 has an upper water inlet opening normally closed by a screw cap o and a drain cock 7 at the bottom thereof. r[he water in the trough l. will, of course, become heated trom the llame et the slow, but water let in the trough 2 is cool. The troughs are brought end to end, the trough l having its inner corners provided with hooks 8 to engage upturned lips 9 ou the top 'at the confronting end ot the top 2. The trough l also has itsy outer sides l'orme l with projecting ears il, the same being or metal and designed to exert a tension against the sides/of the trough 2.

lVhen a loaf of bread is 'wrapped in wareifl paper, the longitudinal seam or Yfold ot the paper .is-positioned so that the same will contact with the lower walll ot the trough and the end folds are arranged so that they will Contact with the inner walls olf the said trough 1. The operator moves the wrapped bread through thetrough l, and the heat therefrom will partly melt the *ax at the wrapped or folded end oi. the `wrapper create an adhesive agent at the said folds. T his agent is cooled and. hardened by vile'contact'. with the cool walls and bottoni the trough 2 in the passage ot'v the. bread through said trough, and in this manner it will be noted that bread wrapped in waxed paper may 'be effectively sealed in an expeditious manner by simply passing the same through the trough.

Preferably the outer and inner corners of the trough l are disposed at angles provide a flared entrance mouth to the trough, and while l have herein illustrated and described a preferred embodiment o1?. the'improveniont as it now appears me,

il D

it is to he understood that l hold myself (entitled to such changes therefrom as full Within the scope ot what l claim Without departing from the spirit of the invention.

Having described the invention, I claim?- 1. In u device lor the purpose set Jforth, troughs, each comprising a hollow shell including a straight buse and angle sides, ineens for removably connecting the confronting ends of the troughs, each of said troughs comprising a water container, and the water in one of said containers designed to be heated.

2. In a. device for the purpose set forth,

two aliffning troughs eachy comprising :L hollow sthell, hooks on the end of one trough, lips on the ends of the adjacent troughto be engaged by said hooks, resilient means projecting from the sides of one trough for contacting the sides of the confronting trough,rnor1nally closed means for admitting water into both of the troughs, 'means for heating the Water in one of the troughs, a, safety vulve for said trough, und a water outlet valve for the other trough In testimony whereof I affix my signature JAMES B.RoBB1Ns.
